GAS-REGULATOR FOR SELF-'GFNERATIN G STEAM-RADIATORS.

Specification o1 LetteIsIlatent. m

Patented 'oea e, 1914.

Application filed November 8, 1918. Serial No. 799,875.

To all whom it may concern a i Be it known that I, JOHN S. SIMMONS, a citizen of the "United States, residing in the borough of Brooklym'county of Kings, city and State of New York, have invented a new and useful Improvement in Gas- Regulators for Self- Generating Steam-Radiators, of which the following is a speci-' fication.

My invention relates to the class of steam radiators, of which one species is shown in the application for patent of George W. Noble, filed February 21, 1913, Serial 'No', 749,875, in which a gas burner is arrangedto heat a water containingmember oftlie radiator serving as a boiler, so as to generate steam therein, and the flow of gas through the supply pipe is automatically regulated by the steam pressure acting on a'sprm pressed pressure diaphragm, which pontro s the gas supply valve, so that no more gas will be consumed than is necessary to ma1n-. tain the desired pressure in and heat from the radiator.

My present invention consists of novel means for adjusting the tension of the spring acting on the valve-carrying diaphragm, to suit difierent gas pressures and also the desired steam pressure, as hereinafter set forth.

In order that in) invention may be fully understood 1. shall: first describe, in detail the mode in which "I have carried the invention into practice and then particularly point out the invention in the claims.

Reference is to be had to the accompanying drawings forming part of this specification in which like parts are designated by the same numbersthroughout.

Figure 1 is a sectional view showing the gas regulating valve in which I have reduced my invention to practice. Fig. 2 is a cross-sectional; view of thesame on the line 22, Fig. 1.1

- In the drawings, 1 is the lower steam 'ne'rating member orboiler-ofthe radia r; 2 is the chamber containing the diaphragm carrying the gas regulating valve 3; 4 .is

the pipeconnecting the boiler with the steam side of the chamber 2 5 1sthe gas inlet pipe leading into the-gas side of the chamber 2; 6 is the gas out-let pipe leading outward therefrom through a tube 7 protruding from the wall of the gas chamber toward the valve 3, the open end of which tube 7 forms the valve seat; 8 is the spring coiled around the protruding tube 7 and pressing against the diaphragmatic valve 3 against the steam pressure on the other side thereof; and 9 is the gas burner fed by the gas outlet pipe 6 to heatthe boiler 1. In the resent case the protruding gas tube 7 is xed to the chamber ,wall.

rounding the base of the tube 7, the collar having diametrically opposite arms 13 and 14, working in corresponding recesses on opposite sides of'the recess 12.

Against the arm 13 of the spring compressing member 10 bears the inner end of an adjusting screw 15 projecting through A and threaded in the wall of the chamber, so that by turning the screw 15 from the outside, the spring compressing member 10 can be swung on the end of its arm 14 acting as a pivot, to compress the spring 8more or less axially and thus vary the resistance of the valve diaphragm to the steam pressure more or less as desired. I also adjusting the by-pass 16, which in this case rovide for leads from the gas inlet to the gas outlet around the valve 3, by forming in the byass a valve seat 17, whichis adapted'to closed by the end of an axiall ad ustable screw 18 acting as a valve an projecting through and threaded in -thewall of the by-pass, so that by turning the screw 18 the by-pass can be opened more or less to suit the gas pressure.

I claimas my invention:

- The combination, with" the chamber having two heads, the valve diaphragm therebetween, the pressure pipe leading through compressing the spring axially, and an ad- 011118 l1(i11d,.an((11 the gas tllllbe plrojeiztinlg1 from justing screw acting on said lever arm.

t e 01: er hea toward t 6 Va ve iap ragm, 4 of an axially movable collar embracing the JOHN SIMMONS 5 gas tube, a spring coiled on said gas tube In presence of between the valve diaphragm and the col-- PHILLIP WIEGAND, lar, a lever arm for moving said collar and. CLARENCE L. BURGER.
